Abstract

With the increasing awareness of environmental protection and sustainable manufacturing, the energy consumptions and potential environmental impacts of laser additive manufacturing (LAM) technology has been attracting more and more concerns. This paper firstly investigates the energy distributions of different modules of laser engineered net shaping (LENS), studies the effects of input variables (laser power, scanning speed, and powder feed rate) and kinds of powders on the overall energy consumption during laser deposition processes. The Energy Consumption of Unit Deposition Volume (ECUDV, in J/mm³) is proposed as a measure for the average applied energy per volume of deposited material. The experimental results suggest that the powder feed rate has the largest effect on ECUDV, followed by scanning speed and laser power. When the geometry shaping is selected as an evaluating criterion, AISI 4140 powder will cause the largest energy consumption per unit volume.
